Napco䴜s crystal-control Gemini wireless products have been proven by an independent testing laboratory to outperform competitive products, with long-range RF reliability, as much as 50% higher than other brands.

Gemini Transmitters range from keyfobs and panic buttons, to recessed door and surface-mount window/door contacts, to wireless PIR, PIR/pet and dual sensors, and from wireless smokes and glass breaks to heat detectors. Simply put, Gemini䴜s uncommon crystal-control precision and omnidirectional circuitry, ensures the wireless/hardwire systems you provide your customers will dependably deliver the security and trouble-free, peace-of-mind they deserve for many years to come.

Gemini products are also meticulously engineered with your needs in mind, too. All Gemini panels and receivers seamlessly support the full line of Gemini transmitters and virtually all panels, keypads, receivers and peripherals are compatible with each other and work the same, model to model.
